Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, and in particular to a pot support and a gas stove. Background Technology

[0002] Traditional pot supports often use a fixed ring structure, such as a windproof pot support or a basin-shaped pot support. Although they can support the pot, the flames can easily escape from the gap between the bottom of the pot and the pot support, resulting in a large amount of heat loss. Only a small portion of the heat is applied to the bottom of the pot. The heat dissipation is accelerated after the smoke comes into contact with the inner wall of the pot support, and the thermal efficiency is significantly reduced. Utility Model Content

[0003] The purpose of this invention is to provide a pot support that solves the problem of thermal efficiency of traditional pot supports by extending the residence time of high-temperature flue gas between the pot support and the bottom of the pot, thereby reducing heat loss and improving thermal efficiency.

The plurality of vortex generating parts are fixedly arranged on the guide surface at an annular interval.

[0006] According to one embodiment of the present invention, the eddy current generating part includes a cylindrical protrusion, the lower end of which is connected to the guide surface.

[0007] According to one embodiment of the present invention, the guide surface is provided with a plurality of mounting holes, and the lower end of the cylindrical protrusion is fixedly connected to the mounting holes.

[0008] According to one embodiment of the present invention, the eddy current generating part further includes an eddy current generating plate, which is installed on the top of the cylindrical protrusion or on the side of the cylindrical protrusion facing the fire hole, and the cross-section of the eddy current generating plate is arc-shaped or V-shaped.

[0009] According to one embodiment of the present invention, the concave side of the vortex generating plate faces the edge of the support body, and the convex side of the vortex generating plate faces the center of the fire hole.

[0010] According to one embodiment of the present invention, the eddy current generating part is a plate, which is arc-shaped or V-shaped, with the concave side of the plate facing the edge of the support body and the convex side of the plate facing the center of the fire hole.

[0011] According to one embodiment of the present invention, multiple vortex generating parts are divided into multiple groups of three, with the three vortex generating parts in each group arranged in a triangular pattern.

[0012] According to one embodiment of the present invention, the guide surface gradually rises from the fire hole to the outer edge.

[0030] like Figure 1-8 As shown in the figure, a pot support according to an embodiment of the present invention includes a support body 1 and a plurality of vortex generating parts 2. The support body 1 has a fire hole 11 in the center and a guide surface 12 extending from the fire hole 11 to the outer edge of the support body 1. The plurality of vortex generating parts 2 are fixedly arranged in a ring at intervals on the guide surface 12. When high-temperature flue gas flows through the vortex generating parts 2, it forms a vortex, thereby prolonging the residence time of the high-temperature flue gas between the pot support and the bottom of the pot, thereby reducing heat loss and improving thermal efficiency.

[0031] like Figure 1-2 As shown, in a preferred embodiment of the present invention, the vortex generating part 2 includes a cylindrical protrusion 21. The lower end of the cylindrical protrusion 21 is connected to the guide surface 12. When the high-temperature flue gas flows through the cylindrical protrusion 21, the boundary layer separates, forming a Karman vortex street, thereby improving convective heat transfer.

[0032] like Figure 2As shown, in a preferred embodiment of this utility model, the guide surface 12 has multiple mounting holes 121, and the lower end of the cylindrical protrusion 21 is fixedly connected to the mounting hole 121. For example, the mounting hole 121 is a threaded hole, and the lower end of the cylindrical protrusion 21 has an external thread adapted to the threaded hole. For example, the lower end of the cylindrical protrusion 21 is interference-fitted with the inner wall of the mounting hole 121. For example, the lower end of the cylindrical protrusion 21 is non-detachably welded to the mounting hole 121.

[0033] like Figure 1-2 As shown, in a preferred embodiment of the present invention, the upper end of the cylindrical protrusion 21 is hemispherical to further enhance the vortex effect.

[0034] In a preferred embodiment of this utility model, both the flow guide surface 12 and the cylindrical protrusion 21 are coated with an enamel heat insulation layer to improve the service life of the pot support.

[0035] like Figure 3-7 As shown, in a preferred embodiment of the present invention, the eddy current generating part 2 further includes an eddy current generating plate 22, which is mounted on the cylindrical protrusion 21. The cross-section of the eddy current generating plate 22 is arc-shaped or V-shaped.

[0036] When the cross-section of the vortex generating plate 22 is arc-shaped, the inner arc side of the vortex generating plate 22 faces the edge of the support body 1, and the middle apex of the outer arc protrusion side of the vortex generating plate 22 faces the center of the fire hole 11, so that the high-temperature flue gas is diverted from the apex of the outer arc surface of the vortex generating plate 22 to both sides.

[0037] The vortex generating plate 22 is located on top of the cylindrical protrusion 21, or the vortex generating plate 22 is fixed to the side of the cylindrical protrusion 21 facing the fire hole 11 by screws 23. When the high-temperature flue gas flows through the vortex generating plate 22, the boundary layer separates to form a Karman vortex street, thereby improving convective heat transfer.

[0038] When the cross-section of the vortex generating plate 22 is V-shaped, the side of the vortex generating plate 22 with the groove faces the edge of the support body 1, the middle part of the vortex generating plate 22 with the protrusion faces the center of the fire hole 11, and the cylindrical protrusion 21 is located between the two side walls of the V-shaped vortex generating plate 22.

[0039] like Figure 3-7 As shown, in a preferred embodiment of this utility model, the vortex generating part 2 is a plate, which is arc-shaped or V-shaped. The concave side of the plate faces the edge of the support body 1, and the convex side of the plate faces the center of the flame hole 11. This embodiment is basically the same as the above-described embodiment, except that: in this embodiment, the lower end of the plate is directly fixed to the guide surface 12, and the cylindrical protrusion 21 is not provided, thereby reducing the amount of material used.

[0040] like Figure 1-5As shown, in a preferred embodiment of this invention, multiple vortex generating parts 2 are grouped into multiple groups of three, with the three vortex generating parts 2 in each group arranged in a triangle to enhance convective heat transfer. For example, one of them is close to the fire hole 11, and the other two are close to the edge of the support body 1.

[0041] like Figure 8 As shown, in a preferred embodiment of this utility model, the guide surface 12 is an inclined surface, gradually rising from the fire hole 11 to the outer edge to increase the space between the pot bottom and the guide surface 12, allowing for sufficient convection of the high-temperature flue gas. The outer edge of the guide surface 12 is bent downwards to form a side wall 13, and the inner edge of the guide surface 12 is bent upwards to form a flame-guiding fold 14. For example, the angle between the guide surface 12 and the side wall 13 is 40-80 degrees, and the angle between the guide surface 12 and the flame-guiding fold 14 is 100-140 degrees.

[0042] like Figure 2 As shown, in a preferred embodiment of this utility model, a plurality of cookware support arms 3 are also included. The plurality of cookware support arms 3 are installed at intervals on the bracket body 1, further increasing the space between the bottom of the pot and the guide surface 12.

[0043] For example, the diameter of the cylindrical protrusion 21 is 2-15 mm, and the radius of the vortex generating plate 22 is 3-20 mm.

[0044] This utility model also provides a gas stove, which includes a gas stove body and at least one of the aforementioned pot supports. The pot support is disposed on the gas stove body, and the burner holes correspond to the burner heads of the gas stove body. Because this utility model uses the aforementioned pot support, it extends the residence time of high-temperature flue gas between the pot support and the bottom of the pot, thereby reducing heat loss and improving thermal efficiency.
